Application Details

Compatible with 2001-2006 Chrysler Sebring rear upper and 2001-2006 Dodge Stratus rear upper. This Delphi TC4275 ball joint is also cross-referenced to MOOG Chassis Products K7346 and Mevotech Supreme MK7346 for the same application. For Chrysler Sebring and Dodge Stratus suspension repair, TC4275 provides an OE-style replacement built around Delphi’s dimensional and material analysis for fit consistency.

What It Helps Repair

• Excessive suspension looseness or play at the rear upper joint
• Clunking or knocking from worn ball joint components
• Uneven rear suspension articulation
• Steering and handling issues caused by worn suspension linkage
• Dust boot failure that can expose the joint to contamination

Installation Notes

TC4275 is a press-in ball joint, so proper removal and installation tools are recommended. Verify the rear upper position before ordering, and confirm thread direction, stud taper, and dimensions against the original part. This part is listed for power steering applications and uses a 6 mm wrench size on the stud.

Quality Assurance

Delphi applies OE-focused testing and dimensional analysis to its steering and suspension parts. According to the manufacturer, components are evaluated across extreme temperature ranges and salt-spray exposure to support durability in real-world service conditions.
